Leukorrhea occurs with conception after ovulation. If a woman conceives after ovulation, resulting in an increase in leukorrhea, it is a normal physiological phenomenon. This is because after the fertilized egg is deposited, there are changes in the hormone levels in the woman’s body, such as an increase in the level of estrogen, which causes vaginal or pelvic congestion, and this leads to an increase in vaginal secretions, that is to say, an increase in the amount of leukorrhea. However, during the period of conception after ovulation, the increase of leukorrhea caused by pathological factors is not completely ruled out, such as vaginitis, which can also lead to an increase in leukorrhea, and its trait will be different from that of the normal secretion of the leukorrhea, which may have a bad smell, and the leukorrhea will become yellowish or foamy, tofu-dregs, and so on. When leukorrhea occurs after ovulation and conception, attention should be paid to distinguishing physiological leukorrhea from pathological leukorrhea. Once abnormal leukorrhea is detected, it is recommended to go to a regular hospital for consultation and treatment as soon as possible.
